Cistoadenoma gigante de ovario y embarazo

The presence of a giant ovarian tumor in pregnancy is very rare, these masses are usually asymptomatic and are detected incidentally on the ultrasound examination of the first trimester or until they reach a large size, whose removal can be performed during cesarean section. We present a clinical case of a 34-year-old female patient, 36 weeks pregnant, who presented a giant ovarian tumor evidenced during the emergency cesarean section, a live newborn was obtained and a giant tumor of the left ovary was present that measured 22 x 17 cm in diameter. An elective cesarean section can be chosen along with salpingo oophorectomy in case of a giant ovarian cyst that complicates a full-term pregnancy as in the case presented. Ultrasound continues to be the most important tool in the study of adnexal masses due to its safety, availability and accuracy; however, the definitive diagnosis is granted by histopathology. The use of magnetic resonance imaging can also be used, to help distinguish benign tumors from malignant ones more accurately during pregnancy. It is important to carry out prenatal control and strict monitoring of the tumor, to decide the time of surgical treatment, in order to avoid maternal or fetal complications.
